Another object of this invention is to provide an improved frame structure of simple construction requiring a plurality of identical elements whereby it may be economically manufactured.

A further object of this invention is to provide an improved frame structure which may be utilized in the construction of either a batterboard or a scaffold, said frame structure being easily and quickly assembled, or knocked-down, whereby it may be conveniently stored.

With these objects definitely in view, the invention resides in certain novel features of construction, combina- States Patent tion and arrangement of elements and portions as will be hereinafter described in detail in the specification, particularly pointed out in the appended claims, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a perspective view of a batter board formed from the universal frame structure mentioned above and showing the arrangement of various line driving and holding elements thereon;

Figure 2 is an enlarged perspective view of one of the line holders and clearly showing the details thereof;

Figure 3 is an enlarged perspective view of a plug element which is adapted to be inserted in the open end of one of the standards forming a portion of the batter board construction of Figure 1;

Figure 4 is a perspective view of the lower portion of a scaffold formed of a plurality of the universal frame structures, such as utilized in forming the batter board construction of Figure 1;

Figure 5 is an enlarged perspective view of one of the foot elements adapted to be received in the open end of one of the standards forming a portion of the scaffold of Figure 4; and,

Figure 6 is an enlarged perspective view of a connecting pin adapted to be disposed in the upper end of one of the standards forming a portion of the scaffold of Figure 4 and adapted to connect vertically aligned standards of adjacent levels of scaffolding.

Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the different views of the drawings.

Referring now to the drawings in detail, it will be seen that there is illustrated in Figure l a batter board which is referred to in general by the reference numeral lit. The batter board it is a vertically extending structure including two panel portions at right angles to each other and includes a corner standard 12 and end standards 14. The standards 12 and 14 are identical in construction and differ only in their position in the batter board 10. Each of the standards 12. and 14 includes a vertically extending elongated tubular portion 16 which has telescoped within its lower end and extending therefrom a pointed foot element 18. The foot element 18 extends well up within the tubular member 16 and is secured in same by a wing set screw 20. It will be noted that the foot element 18 has a pointed end due to the fact that it is necessary for the batter board to be firmly set in the ground adjacent the building being constructed.

Welded to the upper end of the tubular member 16 is a generally circular horizontal plate 22 having arms 24 extending therefrom at substantially right angles to each other. Extending between the upper ends of adjacent standards 12 and 14 are channel shaped horizontal frame members 26. The horizontal frame members 26 are provided with a plurality of apertures 28 in their webs adjacent their ends and are secured to the arms 24 by fasteners 30 passing through the apertures 28 and their corresponding apertures 32 in the arms 24.

Disposed below the horizontal plates 22 are vert'ically extending first braces 34 which have legs 36 at right angles to each other. Each tubular member 16 is provided with a second bracket 38 intermediate its ends, said second bracket having legs 40 at right angles to each other.

The standards 12 and 14 are additionally secured to each other by diagonal bracing members 42 which are in the form of an elongated tubular member having flattened ends 44. It will be noted that each bracing member 42 is secured to a leg of one of the braces 34 and 38 at each of its ends by fasteners 46. It will be noted that the bracing members 42 are secured to opposite sides of the legs of alternate brackets 34 and 38 whereby the pair of bracing members 42 between each adjacent pair of standards lie in different planes which are parallel to each other so that the bracing members are in touching engagement only. The bracing members 42 between adjacent standards are secured together at their point of intersection by a pivot pin 48 which permits the bracing members to be moved to a parallel aligned position for storage purposes.

It should also be noted that the legs 36 of the upper or first braces 34 are provided with elongated slots 50 through which the fasteners 46 pass in order that some degree of adjustment may be obtained.

The open upper ends of each tubular member 16 is closed by a cap pin 52 which is removably mounted therein. The cap pin 52 is clearly illustrated in Figure 3 and includes a shank portion 56 and an enlarged head 54. It will be understood that a batter board is mounted in the ground at each corner of a building to be constructed and that lines are stretched between adjacent batter boards for aligning the foundation and the walls of the building. Each horizontal frame member 26 is provided with at least two line holders which are referred to in general by the reference numeral 58. As is best illustrated in Figure 2, the line holder 58 is formed of a short length of channel stock and has a web 60 and flanges 62 and 64. Welded to the upper side of the web 60 is a vertical plate 66 having a plurality of spaced parallel line receiving slits 68 therein. In order that the line may be firmly secured after passing through one of the slits 68, the flange 64 is provided with a cleat 70 around which the line may be engaged to retain said line under tension. it will be understood that the flange 64 is provided with two such cleats 70.

It will be understood that the line holders 58 may be slid along the horizontal frame member 26 to their desired position. After the desired position has been reached, the individual line holder is clamped to the horizontal frame member 26 by a thumb screw 72 carried by the flange 62.

Referring now to Figure 1 again, it is seen that one of the flanges of each of the channel shaped horizontal frame members 26 is provided with a downwardly extending mounted block 74 adjacent each of its ends. Pivotally secured to one of the mounting blocks 74 by a pivot pin 76 is an elongated rod member 78 having an upturned end portion 80 which is secured by the pivot pin 76. The other mounting block 74 has pivotally secured thereto by pivot pin 82 a tubular L-shaped bracket 84. It will be noted that the free end of the elongated mounting rod 78 is removably mounted within the free end of the L-shaped mounting bracket 84. Slidably mounted on the elongated mounting rod 78 are reels 86 containing reeling lines thereon. It will be understood that there is one reel for each line holder 58.

In view of the foregoing, it will be seen that once the batter board has been mounted at the corner of a building site, reels 86 having lines reeled thereon, may be mounted on the elongated rod 78 and the line unreeled therefrom and secured to line holders 58 with the line extending between batter boards 19 of adjacent corners.

Referring now to Figure 4 in particular, it will be seen that there is a scaffold structure referred to in general by the reference numerol 110. The scaffold 115) includes a lower section 160 and an upper section 102.

The section 100 includes four identical standards, arranged to form a substantially square structure, the standards being all identical are referred to by the reference numeral 112. Each of the standards 112 includes a vertically extending tubular member 116 which has received in its lower end a foot element 118. As is best illustrated in Figure 5, the foot element 118 includes a shank 88 and an enlarged ground engaging end 90.

The upper end of the tubular member 116 is also open and has telescoped therein a joining pin 92. As is best illustrated in Figure 6, the joining pin 92 has an enlarged 4 central portion 94, a lower end shank 96 and an upper shank 98. The lower shank 96 is secured within the upper end of the tubular member 116 by a set screw 104.

Secured to the upper end of the tubular member 116 is a substantially circular horizontal plate 122 having arms 124 extending therefrom at right angles to each other. It will be noted that the horizontal plate 122 surrounds the upper portion of the lower shank 96 and directly underlies the enlarged central portion 94 of each of the joining pins 92. Extending between and secured to the arms of the horizontal plates 122 of adjacent standards 112 are horizontal frame members 126. The horizontal frame members 126 are secured to the arms 124 of the horizontal plates 122 by a plurality of fasteners 130.

Each tubular member 116 is provided adjacent its upper end with a vertically extending first bracket memher 134. The first bracket member 134 is provided with legs 136 at right angles to each other.

The tubular member 116 is also provided with a second vertically extending bracket 138 having legs 140 at right angles to each other. Extending between the brackets 134 and 138 of adjacent vertical standards 112 are diagonal bracing members 142. The bracing members 142 are preferably made of tubular material and have flattened ends 144 which are secured to the legs of the brackets 134 and 136 by fasteners 146. It will be noted that the bracing members 142 extending between adjacent standards 112 are connected together by pivot pins 148 to form a generally X-shaped brace. Furthermore, the bracing members are secured to the opposite sides of the legs of alternate brackets whereby the two bracing members which form each X-shaped brace are in face to face contact only.

It will be noted that the standards and bracing members of the upper section 102 of the scaffold 110 are identical to the standards and bracing of the lower section and need not be described in detail. However, it will be noted that the lower ends of the standards of the upper section 102 have telescoped in their lower ends the upper shank portion 98 of the connecting pins 92 whereby the upper and lower sections of the scaffold are rigidly secured together.

It will also be noted that the standards 12 and 14 are identical to the standards 112 so that the standards may be utilized to form either a batter board as illustrated in Figure l or a scaffold as illustrated in Figure 4. Also the bracing members 42 are identical and interchangeable with the bracing members 142. In order that the standards 12 and 14 may be utilized in the scaffold 110, it is merely necessary to remove the pointed foot element 18 from the lower end of the standards and insert in place thereof a foot element 118.

It should also be noted that the horizontal frame members 26 and 126 are of the same construction with the exception that the horizontal frame member 26 has provided thereon means for holding lines. Although the horizontal frame member 126 could not be utilized in the construction of a batter board, it is obvious that if it is necessary, the horizontal frame member 26 could be utilized in the construction of a scaffold similar to that illustrated in Figure 4.

While the description of the batter board of Figure 1 has been limited to the use of line, it should be understood that the invention is not so limited in that the material utilized with the holders 58 and the reels 86 may be wire, chalk line, or other suitable materials.

The interchangeability of the various frame elements of the batter board and the scaffold will be readily understood from the foregoing description of the details thereof, taken in connection with the above recited objects and drawings. Further description would appear to be unnecessary. Minor modification of the batter board and scaffold-varying in minor detail from the embodiinent of the invention illustrated and described may be resorted to without departure from the spirit and scope of the invention, as defined in the appended claims.
